SS7 is a standard protocol to initiate a calling connection with SPC exchange.

Notes:

1. “Trunk No.” is a shared data, therefore, SS7 „Trunk No.‟ can't be the same as PRI “Trunk No.”

2. SPC length is 24bits when option “ANSI” or “ITU-CHINA” is selected in item “Standard Type”.

3. SPC length is 14bits when option “ITU” is selected in item “Standard Type”.

4. SPC Length represents the structure of OPC/DPC. SPC View Mode indicates which input

format is selected for OPC/DPC structure.

5. When SPC length is 24bits and 'Hex' are selected, the structure is like xyz, and x,y,z must be

hex number between 00-FF. eg., 33AA55.

6. When SPC length is 14bits and 'ITU Pointcode Structure' are selected, the structure is like

x-y-z, and x,z must be decimal number between 0-7, and y must be decimal number between

0-255. eg., 6-222-3.

7. When SPC length is 14bits and 'Hex' are selected, the structure is like xyz, and x/z is a 3 bit hex

number, y is a 8 bit hex number. eg., 202E(100 00000101 110).

SS7 trunk add

Select Trunk No

The number of SS7 trunk. Generally, a DPC will establish a SS7 trunk number

respectively, SS7 trunk number cannot be conflict with PRI trunk number. After

SS7 trunk is established, assign E1/T1 to SS7 trunk in “SS7 Circuit” option.

Trunk Name

Name of trunk, it can be edited to any name user want.

Protocol

SPC types: ITU-T (14 bit), ANSI (24 bit), ITU-CHINA (24 bit)

Protocol Type

Supported two protocol types: ISUP and TUP

SPC Format

Signaling Point Code format includes hexadecimal system and ITU pointcode

structure (decimal system)

OPC

Original Point Code

DPC

Destination Point Code

Service Type

SS7 service types: ISUP (ISDN User Part) and TUP (Telephone User Part).

Network Indicator

Indicate the network property of SS7, including International Network,

International Spare, National Network, National Spare; the default is “National

Network” (this type is used in China, USA, and Japan), “International Network”

is generally used in inter-office switch room; others will be selected according

to physical circumstances.

Note：

1. If protocol standard chose 'ANSI' or 'ITU-CHINA', and then the SPC length is 24 bits.

2. If protocol standard chose'ITU', and then the SPC length is 14 bits.
